Cassava starch is modified to increase porosity and lacerations that are limited when only enzymatic treatments used. This study proposes improve activity of α-amylase amyloglucosidase on the polymer chains cassava by implementing physical thermal pretreatments below gelatinization temperature before hydrolytic process. The increased biocatalytic action enzymes, causing significant changes in m...

Surplus bread is a major bakery side stream that should be strictly kept within the human food chain to reduce waste and ensure resource efficiency in baking processes. Optimally, surplus recycled as dough ingredient, however, this known detrimental volume texture of bread. The purpose study was investigate how gelatinized starch bread, untreated or enzymatically hydrolyzed, affects development...

Abstract The purple sweet potato starch was the only carbohydrate component that converted to its monomeric sugar during conventional saccharification process, while fiber remained because α-amylase and amyloglucosidase act on α-1,4 α-1,6 glycosidic bonds in starch. To overcome this, xylanase mannanase are used convert hemicellulose sugars. optimal conditions process must be known achieve liqui...

Five steam-flaked sorghum grain (SFSG) samples with bulk densities of 476, 412, 347, 309 and 283 g/liter made by adjusting tension between mill rollers and three reconstituted sorghum grain (RSG) samples with reconstitution times of 10, 20 and 30 d and a control sample were analyzed for gas production kinetics (rumen liquor fermentation) and enzymatic glucose release (amyloglucosidase). Protein...

A small-scale mashing (SSM) procedure requiring only 300 mg of samples was investigated as a possible method of predicting ethanol yield of sorghum grain. The initial SSM procedure, which was conducted similarly to the mashing step in a traditional fermentation test, hydrolyzed just 38.5–47.2% of total sorghum starch to glucose. The initial procedure was simplified to contain only one liquefact...

Despite the presence of a rutinosyl group at 3-OH, aqueous solubility flavonoid rutin is even lower than that its aglycon quercetin. In this work, we describe fast, simple, and easily scalable process for polyglucosylation to enhance solubility, catalyzed by cyclodextrin glucanotransferase (CGTase). Several reaction parameters (source enzyme, rutin/starch weight ratio, cosolvent, pH, temperatur...

Green zinc-metal-pillared bentonite mediated curcumin extract (Zn@CN/BE) was synthesized and characterized as a low-cost multifunctional (curcumin-based phytochemicals, zinc-capped curcumin, zinc/curcumin complexes, zinc-pillared bentonite) antioxidant antidiabetic agent with enhanced activity. The activities of the Zn@CN/BE structure were assessed in comparison ZnO individual components presen...
